Upgrading PHP Mailer from 5.2.7 to 5.2.14 and use 3rd party API calls

[fdohmann]

Many WHMCS installations using shared servers at HostGator. The problem is sending mail using shared IP Blocks of HostGator's mail server "cima.websitewelcome.com" like invoices or invoice reminders created by the WHMCS cron never arrive at the recipients mail box. They get, typical for HostGator, their email blocked by "http://emailadmin.registeredsite.com/" caused by spammers in the neighborhood using the same "cima.websitewelcome.com" IP block. This is damaging to our cash-flow.

 

The solution would be to use an API call through a 3rd party mail service provider like "Sendgrid", "Mailgun" or "Mailjet" and bypass the HostGator "cima.websitewelcome.com" mail server. It works great with a single WHMCS email template when properly coded, but it will not work with the daily WHMCS cron job responsible for creating invoices, invoice reminders and overdue messages:( We use the WHMCS -> Mail -> Type PHP Mail() with SMTP Port 465, Host: smtp.sendgrid.net with our username and password (see also https://github.com/PHPMailer/PHPMailer). The modified "class.phpmailer.php" mailer still uses "cima.websitewelcome.com" as it's initial sender. The perfect solution would be to upgrade the WHMCS "class.phpmailer.php" from 5.2.7 to version 5.2.14 and add a "Sendgrid API client" to bypass the HostGator Mail Server, like the Google XOAUTH2 Api client (as an option available) to the internal WHMCS Mail Service.

I have created an addon for WHMCS, that allows you to send all your emails directly to sendgrid, or mailgun via their HTTPS API, and bypass SMTP altogether. It requires only adding 1 line of code to the "class.phpmailer.php" file.

Also included is the ability to track all emails (dropped, bounced, received, opens, clicks) via a webhook back into your WHMCS installation.

 

The OP is currently beta testing, and I am looking for 1 or 2 more users to test. Please PM me if interested.

 

Thanks!
